PLATE FOR PIANOS.

SPECIFICATION formingpart of Letters Patent No. 745,103, dated November24, 1903.

Application filed March 27, 1908.

To all whom it may concern:

Be it known that I, CHARLES A. HADDORFF, a citizen of the UnitedStates,residing at Rockford, in the county of lVinnebago and State ofIllinois, have invented certain new and useful Improvements in Platesfor Pianos, of which the following is a specification.

The object of this inventionis to construct a string-plate for pianosand similar musical 1o instruments in which there is provided an offsetportion and an abutment for the purpose of supportingthe wrest-plate, sothat the strain of the wires will be sustained by the said abutment andin direct alinement with the plane of the main portion of the plate.

In the accompanying drawings, Figure 1 is a perspective View looking atthe front of my improved plate. Fig. 2 is an edge view of one end of theplate, showing the offset and abutment formed thereby.

The string-plate comprises the hitch-plate 2, that is supported by theseveral braces 3, 4, 5, and (3. The support '7 for the base-wiresextends from the brace member 5 to the lower end portion at the end ofthe brace memberS.

At one end of the plate, which is preferably the upper end in what areknown as upright pianos, is an integral extension 1, that is offsetforwardly from the adjacent portion of the plate and extends throughoutthe whole Serial No. 149.857. (N0 model.)

length thereof. This forwardly-offset extension forms an abutment orledge S at the rear side of the plate that is located at right angles toand in direct alinement with the front side of the main portion of theplate.

hen the wrest-plank is secured to the extension 1 its face or edge willengage and rest upon the abutment-face 8. Consequently the strain of thewires on the wrest-plate is borne upon this abutment S and in adirection co- 4o inciding with theplane of the front side of the plate.This construction will overcome any tendency of the tension of the wiresto spring or buckle the plate and also to spring the wrest-plank awayfrom its attachment to the plate.

What I claim is A string-plate for musical instruments having anintegral f0rwardly-extending offset portion extending entirely acrossthe upper end of the plate and forming an abutment or ledge on the rearside of the plate for engagement with the wrest-plank, the inner edge ofsaid abutment or ledge being in the same plane with the front side ofthe main portion 5 5 of the plate.
